i these lugs' and are seriai No.44d49a Y are not shown in the drawings. The entire .Vlithirr Vthe refrigerator 10 is mounted a single inner shell 18 which `occupies lvthe interior of therefrigerator and consists'jof a back 19, two sides 20 'and 21, atop 22, a`

front '24 which follow the surfaces of the inner. walls 11. The front 24 is formed withopenings 25, 26, and 27 which correspond to the openings l5 inv the front wall 14 vofthe device.', i

a vitreous making the interiorperfectly smooth and Veliminating cracks inf which dirt and moisture' may collect, .thereby making thefrefrigerator vperfectly sanitary at `alltimes.

The receptacle for ycarrying the ice or refrigerating -means is best shown in Figs. 1 and 2. Across the'inner wall'memberll of thetopof the refrigerator are positioned twoY bars 28 and 29, vinto which arev screwed four rods30, 31, 32 and 33, extending Akdownwardly through holes`35 in theftop 2 2 yof the Shell .'18 and into' the interiory of the refrigerator. Each of these rods is formed with a shoulder 34 whichfcla'm'ps up against the yunder side of the top 2 2'fholding' saidv rods firmlyattached to and suspended from Y interior ofthe device. With this construction, the rod Can be easily Vdetached fromthe top `of the, refrigerator. Atv' the ends of rod's30, 31,32 and 33 the same are held positionedrelative yto eachother by two bars 36 which, have their ends 37 'and 38 connected to the ends of Said are ,screwed on the ends of said-'rods to hold Swayingfof the device is prevented by 1 two lugs 40,'and L11 which are formed ontwocastings, 42' and 43, secured to thewalls 19 and 24 ofthe inner shelllby'bolts 4:7, which pass through holes 58'in Isaid'walls,"as is yclearly shown in Fig. 5. Rods 30and 33 pass directly through held from' movement by V39, which lscrew the aforementio'ned nuts The entire interior. is covered withI fused enamel whch is baked on,

rods, nuts '39 vrefrigeratorpis mounted on legs ,16 which have attached to .them l:castors 17.

- The inner shell' 18 up under said lugs and hold the entire receptacle in place. The shelf on which the ice is placed consists of a number of small channel bars which extend across the members 36 and are securely riveted to a pair of flat cross bars 46 which hold them in spaced relation toA one another. There the flanges of channels 45 rest uponbars 36, said flanges are notched so as to prevent the shelf from sliding off of its support, the bottom of said flanges projecting below the tops of bars 36, as is clearly shown in Fig. 1.

In order to hold the ice in place on top'of the ice" shelf, the entire space'around the ice is' enclosed on three sides by means of a number of sl-ats 47 which rest in sockets 48 formed on the previously referred to rods 30, 31, '32' and 33. Said sockets are formed open atthe top so that the slats may be easily removed for purposes of cleaning, so that the refrigerator may be kept perfectly sanitary. This construction keeps the ice away from the walls of the inner shell and so prevents injury to the enamel due to careless handling of the ice and furthermore p rovides a `space around lthe ice through which the air may circulate,V thus effecting a more rapid cooling effect and a more even temperature.

In refrigerators of the type shown it is customary to separate the food chamber from the ice compartment by a division partition wall running vacross the `same but being open 'at the top and lbottom to permit proper air circulation. I haves'hown such a portion of the louver type which vconsists offtwo sections 49 and50, the former lof which is shown in 'detail in Fig. 4. -A number of transverse horizontal louver bars 5l are secured to two 7 upright channel bars 52 and 53 which are placed with 'inner 'shell by to 'walls 19 and 24 their flanges 'projecting outward and the entire width ofea'ch section 49 and 50 is such that these sections just occupy the entire width of the interior of the refrigerator. The lower section 49 is partly supported by the castings 42 which are provided with 'sockets 54 into Ywhich fit projections 55 formed on the webs of channels 52 and 53 by cutting away portions of the flanges `at 56. In addition to these supports,a pair of channel blocks 57 'are employed which are of such 'size as to pass in between the flanges of channel bars 52 and 53 and which are bolted means of `bolts 59 vwhich pass through holes 63 in said walls.

These blocks are positioned immediately above the sockets 54 and lproject partly above member 49 when the same is in `lplace so as to form a guide for the following member 5 0, which rests directly upon-mem- `bei" 49.

Another pair of channel blocks60 are pivotal'ly 'secured 'to the walls 19 vand 24 of the means of bolts `61 which pass through holes 62 in the inner shell. These of the refrigerator of the'inner Yshell 18 by' members serve to hold the upper partition section 50 in place. In placing the two partitions sections in the refrigerator the lower section 49 is first inserted as shown in Fig. 5, the channel bars 52 and 53 being slid over the channel blocks 60 which are tilted as indicated. Vhen this section has been pushed up towards the top sufficiently so that the lower portion of the same may clear the channel blocks 57, section 49 is swung back to a vertical position and may then be slid down over channel blocks 57, taking the position shown in Fig. l. Succeeding this operation section 50 is applied in the same manmoved for purposes of cleaning and hence makes the refrigerator perfectly'sanitary.

To collect the condensation from the walls and the water from the ice, I employ a drip pan 63 which comprises two body members 64 and 65 whichare held separated from each other to form an air space 66 and which are completely covered by a metal covering 67 which is enameled on the exterior. This drip pan is formed with a raised portion 68 around the edges and is also provided with an outlet 69 through which the water is led into a drain pipe 70 provided with a. trap 71 as best Fig. 1. The drain pipe 70 connects with a pipe 72 which is secured to the inner shell 18 of the refrigerator and passes' directly through the two walls of the refrigerator to the exterior. drip pan consist of an angle iron bar 73 which extends directly across the inner shell of the refrigerator between the walls 19 'and 24 and is rigidly secured thereto by welding or other suitable means. This drip pan is further supported by the 'castings 42 and 43 which have `sockets 74 formed in them into rwhich two corners of said drip pan extend.

The means of supporting the shown in llU A deflecter member 75 is welded or otherwise securely fastened to the wall 2l of the inner lshell v18 and is bent outward from said wall directing any condensation that may collect The advantages of my invention are ma-nifest. An inner shell is provided which may be constructed so as to comprise a lsingle drip pan'dry. lDelecter piece with the entire surface covered with an enamel coating. This inner shell surrounds the ice compartment as well as the space for placing the food so that the entire contents of the refrigerator are housed by a 1,724,546 sanitary and impervious closure. All of the lugs secured to the walls of said refrigerator parts within the refrigerator are easily demountable so that the same may be scalded and cleaned whenever it is found necessary. The cradle for holding the ice is so arranged as to keep the ice away from the walls of the inner shell, thus preventing any injuries to the same when the ice is ice shelf. A pair of castings serve the triple purpose of partially supporting the ice cradle, drip pan and division partition, holding said members in proper relation to one another.

In accordance with the patent statutes I have described the principles of operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof, but I desire tohave it understood that the construction shown'is only illustrative and that the invention can be carried out by other means and applied to uses other than those above set forth within the scope of the following claims:
